It’s been a while since I released the first beta version of the utils so it’s time for some update. This update will mainly focus on sbs1tcp and it will finally bring TCP30003 compatibility mode. Also the current custom data feed will be more stable and reliable. I am planning to release the new version on Monday 13th of October 2008. If you have noticed any strange behavior of the currently released tools please report it here so that I can try to fix it.

Update 1#: Next version will be 2-3 days late due to sunny weather :) I spent the last few days at the airport spotting planes so I haven’t had much time to code.

Update 2# (Oct 25th): I guess you’ve already noticed I’m not the best at estimating time required to acomplish certain tasks.. or rather at devoting my time to one particular thing. I was away for a few days because of my cousin’s wedding, but I’m back and I’ll do my best to do what’s been promised.

The download problems are caused by moving the site to another server. DNS records needs to be updated and some of them had higher TTL values than I thought. All the records should be updated correctly within 24 hours.

It’s been a long time since I promised to release it and some of you might just given up waiting, but I guess there are still at least a few people interested in this project. It’s still beta version and there surely are some bugs left, but feel free to play with it and send reports in case you spot some strange behaviour. More information about the project is available in the Projects-SBS1 Utils section.

A request: I’ve been receiving quite a lot of emails regarding SBS-1 related stuff.. It might happend I haven’t replied to all of you. In that case please send your email again and I will do my best to reply asap.

As you might have noticed the release got somehow delayed. I have come across some unexpected frames I thought the box itself would take care of. This is partly malformed messages and as a result of that fake planes detected by the system. Right now I am waiting for some more ICAO documents which will clear things up for me and hopefully with them I will be able to fix it. Read the rest of this entry »

This is the last progress update before beta version release in July. I’m finally done with data decoding, but I am not done with my exams yet :/ This week is going to be tough, then my friend’s wedding and on Monday 30th June I should finally be free to code again :) What’s left to be done is TCP 30003 compatible output and some stability tests.

Today I’ve successfully built and run a testing version of SBS-1 software for NSLU2 Linux (SlugOS LE). It’s been working non stop for more than 4 hours now and the CPU usage is below 2.5% (266MHz ARM CPU). This leaves plenty of room for other tasks as web data visualisation and/or data sharing!

It’s been quite a few weeks since the last post so it’s time for updates. During the past few weeks I haven’t had much time for SBS1 as I’ve been working on my university projects + some tasks I had been postponing since I don’t know when :/ I am still working on decoding the RAW data, aircrafts’ positions in particular. AC positions are encoded using CPR ( Compact Position Reporting ) which was not mentioned in the ICAO Annex 10. Luckily doing some Googling I was able to find the necessary docs ( 174+ pages ) and now I will be able to decode it finally :)

In the meantime, while you’re waiting for the standalone application to get data from sbs1 box, I’ve prepared a patch for the latest version of BaseStation .130. You can get it from the downloads section.

I’ve finally decided to merge both my home pages into this blog. This will take a while, but when I’m done I’ll at least be able to keep the site up to date. Using my own code for web sites was fun, but maintaining it was a waste of time :/ From now on I will no longer publish content in Polish. Again, I just want to stop wasting my time translating stuff one way or another.

Maybe there ain’t too many SBS1 owners who’d like to use their boxes under Linux or OS X, but still I think I’m not the only one. This is why I started reverse engineering the BaseStation application and protocol to make an equivalent piece of software that would work *natively* under other operating systems.
